Anyway Michelle Ryan chats with SFX about channelling Joanna Lumley and her preparation for doing a cast of different voices:

“You can’t really prepare. You’re the narrator but you’re also playing these different characters. The challenge is constantly keeping the energy up; keeping the mood up. Sometimes you have top go from being quite energetic and frenetic and then slowing it right down for the next character”

Surely there would be some preparation along the lines of keeping the accents and voices consistent to the characters?

“I’m glad I’ve done it. It gets you thinking – having to switch between different characters, pretty much improvising it as you’re going along.”
